关于电势能几个问题的分析

Problem Analysis of Electric Potential

电势和电势能是静电学部分的重要概念,也是教学的难点.为了使学生准确地掌握电势和电势能的物理意义,需要将一些容易模糊的问题进行梳理.通过对电势能的理论分析,对于理解电势的概念,明确电势是描述电场能的性质的物理量,解释电势能、电势、静电力功的关系有很大的帮助.

The electric potential and electric potential energy is the important concepts in electrostatics.It is also a difficult point in teaching.To grasp the basic concept,some confusing problems need to be clarified.It is of help to analyze the theory of electrical potential energy,to give a clear description of the electric field potential as the nature of the physical quantities of energy and to explain the relationship between the electric potential energy,electric potential and the static electricity power.
